Wisdom in a paragraph

“Good is the enemy of great. And that is one of the reasons that we have so little that becomes great. We don’t have great schools, principally because we have good schools. We don’t have great government, principally because we have good government. Few people attain great lives, precisely because it is easy to settle for a good life. The vast majority of companies never become great precisely because they become quite good — and that is their main problem.”
